ARRANGEMENT OF SPRINGS FOR VEHICLES.

Specification of Letters Patent No. 16,625, dated February 10, 1857.

To all whom it may concern:

Be it known that I, DARIUS BABOOCK, of Homer, in the county of Cortlandtand State of New York, have invented a new and useful Improvement inSprings for Vehicles; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe accompanying drawings, making part of this specification, in which,

Figure 1 is a side or face view of my improvement. Fig. 2 shows amodification of the same.

The invention consists in combining two Csprings with a sinuous spring,as will be hereinafter fully shown and described, whereby a cheap anddurable spring is obtained, and the weight of the body of the vehiclemade to bear upon the ends of the axles, instead of bearing upon theircenter portions, and thereby increasing the strength of the same.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A, repfesents the axle of a vehicle; and B B represent two springs,which are known as C-springs. The lower ends of these springs areattached one at each end of the axle A. The springs B are each formed oftwo leaves, (a) (b), the ends of which are connected together; the outerleaves (1)) having a quicker curve than the inner leaves (a), so that asuitable space is allowed between them.

The upper ends of the springs, B B, are connected by a sinuous spring D,which is formed of a single plate. The form of the spring D is plainlyshown in the drawing; the outer portions or ends (0) (a) being curved tocorrespond with the upper parts of the springs, B B; the center portion(d) being curved in an inverse manner.

The outer ends of the springs B B, have each a curved bar, E, attachedto them; said bars being connected to the body of the vehicle; whichconsequently, is supported by, or rests directly upon, the springs.

Fromthe above description of parts, it will be seen that the spring, Dyields or is elastic longitudinally or lengthwise, and serves as asupport to the springs B, B. And as the bars E are not jointed, but areperfectly rigid, the springs, B B, and D, are each subjected to theirproper share of the weight or pressure; for the outer ends of thesprings, B, rise and fall vertically, as shown in red, Fig. 1, and,consequently, the spring, D is acted upon longitudinally.

The C-spring is usually connected with the body of vehicles by means ofstraps, and these springs have also been connected to semi-ellipticsprings by means of ointed bars or connections. These jointedconnections allow the Csprings to be compressed, or to yield in a spiraldirection; this will be understood by referring to Fig. 2, in which thebars, E, are jointed, and thereby allowed to give, or turn, so as toconform to the action of the C-springs.

It will therefore be seen that in my improvement, it is essential tohave rigid bars to serve as connections between the ends of the springs,B, and the body of the vehicle, in order that the springs, B, and thespring D, may be properly acted upon and each subjected to itsproportionate share of the weight, and a strong, durable, and elasticspring be thus obtained.

I am aware that combinations of C- springs and semi-elliptic springshave been previously used; I therefore do not claim the combination ofthe C-spring with other form of spring, irrespective of the peculiarform and arrangement as herein shown, to produce the result described.

hat I do claim, therefore, as new, and desire to secure by LettersPatent, is

The combination of the C-springs, B B, and sinuous spring, D, connectedby rigid bars, E, to the body of the vehicle, substantially as shown anddescribed.
